The effects of the reinforcing particle size and strain rate on deformation localization behavior of SiC P/6151Al composites are investigated by making use of Split Hopkinson Bar and MTS 810 Materials Testing System with specially designed hat shaped specimens, which can produce a shear loading in the specimen. The experimental results demonstrate that the strengthening effect for the small size particle reinforced composite is higher than that for the large size particle reinforced composite. However, the small size particle reinforced composite is more prone to deformation localization than the large particle composite under impact loading. The mechanisms leading to deformation localization in particle reinforced metal matrix composites are discussed in this paper as well.
